Having initially been introduced in the mid-credits scene of 2014's Captain America: The Winter Soldier, Scarlet Witch finally made her presence truly felt in the Marvel Cinematic Universe in 2015's Avengers: Age of Ultron.
Portrayed by Elizabeth Olsen, the character started the movie as an opponent of the titular heroic super-team, but she soon saw sense and joined them - and she will now be an Avenger in the live action franchise moving forward.
But the character from the comic books on which Olsen's version is based is somewhat different. She was initially introduced as a mutant for starters (although that's been bizarrely retconned to her being a mutate - a human who was experimented on to gain her powers). But what else is there to know about the character that most people won't be aware of?
That's what this article is all about. Here are 10 things you probably didn't know about Scarlet Witch:
10 She Was Introduced As An X-Men Villain
Far from being the heroic member of teams like the Avengers that she is known for being today, when Wanda Maximoff AKA the Scarlet Witch made her first appearance in X-Men #4 in March of 1964, it was actually as an outright villain.
She was actually a part of the Brotherhood of Evil Mutants. Both her and her brother Pietro joined up with Magneto's team of rogues to fight the X-Men in one of the heroic team's earliest adventures. They weren't villains for long, however, and she was soon performing heroics like she is more famous for doing these days.
9 Her Dad Is Magneto
It's easy not to realise this when you only know the movie versions of Scarlet Witch and Magneto - they exist in two entirely different realities in the Marvel Cinematic Universe and Fox's X-Men franchise, after all - but Scarlet Witch is quite famously the daughter of Magneto in the comic books.
It should be noted, however, that this has been reconnected recently - Magneto is now said to be someone she was merely led to believe was her father in current continuity. Classically, however, that is really the case, and the master of magnetism spawned both Scarlet Witch and, of course, her twin brother Quicksilver.
8 She Was Raised By A Cow
Okay, so she wasn't exactly a cow, but she was a cow-like female. When Scarlet Witch's mother, Magda- the wife of the aforementioned Magneto - escaped from her villainous metal-controlling husband, she gave birth to her twins in the Wundagore Mountains. In those mountains, an army of people created by the powerful High Evolutionary had evolved from animals.
One of those animal people - a cow-like woman by the name of Bova - who acted as a nanny and a midwife for the High Evolutionary, took care of Wanda and her twin brother Pietro until the gypsy Maximoff family opted to adopt them.
7 She Married An Android
In spite of the fact that the Marvel comic book version of the Vision is an android - just like the version you may know from the Marvel Cinematic Universe - he and the Scarlet Witch fell in love with each other and got married. The pair even had a limited series together.
If you paid close attention to Avengers: Age of Ultron in 2015, you may even have noticed a couple of moments in which the live action versions of the characters – played by Paul Bettany and Olsen respectively – seemed to express affection towards each other, so be sure to watch that space on the big screen!
6 She Magically Gave Birth To Twins
Although Vision is clearly an android and unable to provide Wanda with children, the powerful character drew on her magic-based powers and was (somehow, don't ask...) impregnated with the Vision's babies. As a result, she gave birth to two boys, Tommy and Billy.
They were linked to Mephisto, however, who reabsorbed their life essence so that the twins ceased to exist. The loss of her children was a major tragedy for the Scarlet Witch that resonates with her to this day. The twins' souls were later reincarnated and the reincarnated versions of them grew into the twin brother and sister heroes Speed and Wiccan.
5 She Tore The Avengers Apart
When the controversial writer Brian Michael Bendis took over the Avengers comic title, he had plans to destroy the team and build it back up again from scratch. In 2004 and 2005's Avengers Disassembled, he did that by wiping out loads of characters in various different ways at the same time.
However, it would later be revealed that all the seemingly coincidental events were actually the doing of the Scarlet Witch. Later stories did ultimately reveal that she was under the influence of a number of supervillains, but it was her massive power that was able to completely tear the team apart - far cry from her classically being a key member of the team.
4 She Effectively Wiped Out Mutants
After the events of the aforementioned Avengers Disassembled, Scarlet Witch was left an emotional mess and beyond help. The Avengers and X-Men gathered to discuss if she should be killed in order to prevent any more catastrophes from occurring as a result of her powers.
Outraged, her twin brother Quicksilver convinced Scarlet Witch to warp reality into a world where mutants are the dominant race. After a long struggle in the House of M reality, she attempted to reverse the effects of her reality-warping by uttering the words "No More Mutants." It reverted the world back to how it was before, but also took the powers away from 90% of the world's mutant population.
3 She Fought Alongside The Evil Dead's Ash
In the five-issue 2007 comic book crossover event that occurred between the Marvel Zombies and the Army of Darkness (aptly named Marvel Zombies vs. The Army of Darkness), Ash Williams - the legendary protagonist, played by Bruce Campbell, from the Evil Dead movie franchise - led a ragtag team of heroes to acquire the Necronomicon in order to fight against the zombie plague.
His most prominent - and unlikely - ally in the event was undoubtedly the Scarlet Witch, who assisted him almost to the bitter end. Unfortunately, she was devoured and transformed into a zombie herself by the zombie version of the Punisher.
2 She Has Been A Part Of A Number Of Teams
Although Scarlet Witch is now classically associated with being a member of the Avengers - having first joined the superhero team way back in 1965 and been in and out of the team ever since - she has in fact been a member of numerous superhero (and supervillain) teams throughout her existence in Marvel's comic books.
In addition to being a member of the standard Avengers team, the complete list of teams of which Scarlet Witch has been a part is as follows; the Avengers Unity Squad, the Brotherhood of Evil Mutants, the Lady Liberators, the West Coast Avengers, the Defenders, the Secret Defenders and Force Works.
1 The Ultimate Version Indulged In Incest
The standard (616) continuity of Marvel Comics isn't the only timeline in the world of Marvel - far from it, in fact, because there are literally hundreds. One of the more famous non-standard timelines is undoubtedly the Ultimate timeline.
The Ultimate line of characters were intended to be an updated and uncomplicated version of their mainstream counterparts. However, Ultimate Scarlet Witch and Quicksilver were very complicated to say the least. Although it was never specifically stated, it's more than heavily implied that the twins are romantically involved with each other. That's right, it's pretty obvious that they indulged in incest. Happy reading!
